Average daily gains were 2.23, 2.28, 1.88 and 2.46 pounds for animals
receiving rations containing 0, 10, 20 and 30 percent dried celery tops, respec-
tively. Steers on the 20 percent celery top ration were the least efficient con-
verters of concentrate and roughage to pounds of gain. Neither carcass nor meat
characteristics appeared to be affected by the inclusion of celery tops in the
rations.

 Dried celery tops contained 25.0 percent crude protein and consisted of
82.8 percent dry matter. Data supplied by four additional steers indicated that
digestion coefficients of the celery material were 77.2, 84.0, 86.1 and 63.4
percent for crude protein, fiber, NFE and fat, respectively.(dry weight basis).
The T.D.N. value obtained was 79.5 percent.

 The results of this study indicate that dried celery tops was a satisfactory
ingredient in a steer fattening ration since gains were as large on a ration
containing 30 percent celery as on a control ration. The digestibility of dried
celery tops was equal to and better than many of the feedstuffs presently used
in cattle rations. It was estimated that dried celery tops were worth between
$55.00 and $60.00 a ton in this feeding trial.
